Specification forming part of Letters Patent, No. 158,72fi, dated January 12, i875; application filed September 3, 1874.

1'0 all whom it may concern:

Be it-known that I, Tnonns PARKIN Moon- WOOD, of Sheffield, in the county of York,

Kingdom of Great Britain and Ireland, have invented Improvements in Molds for (lasting lowing is a specification:

M y invention relates to that class of molds for casting ingots in which two sections hinged Steel or other Metal ingots, of which the foltogether are separable at the corners; and

an ingotmold, A, constrncted according to my invention. Fig. 2 is a front view of the same, and Fig. 3 a plan. Fig. 4C is a View of the mold A, shown open at its bottom or one end, and in the position it will be when the eccentric-lever fastener or holder B is moved, so as to allowfor expansion, or the inold to bedrawn away from the ingot, when such has been cast. g

C is a projecting stem or piece, which may be cast with th'e.eccentric B, or iixed to it;

and which may he of any desired form and length, according vto the size of the'mold and leverage'reqnired to operate the same for expansion or removal. a is a hole, into which may be inserted a bar or other lever for assistance in the moving of the eccentric B from one position to another. b is the pin or stud, upon which the eccentric works. I) are the arms or straps, in which the eccentric B and pin b are carried, and which areplaced and work upon the, projecting pieces E. F are pieces of metal cast with or secured to each half-orpart of the mold, and which work face to face. 6 are pins, which secure the halves or parts together, and upon which the same are hung or dependent. H are ordinary lifting-loops, which are secured in the top side of the mold; and it will bereadily seen that when a chain, hook, or other lifting medium is attached to them, and operated by a crane or other suitable appliance, a pulling or dragging motion, having a tendency to open the mold at the opposite end, as shown in Fig. 4, will be attained; and it' will also be readily observed that ii" the moldA were inverted, the hinges thereby being at the bottom end,

allCLlillQilllOli be dramunouteflthwohh-the action of the mold will be the same, so far as the operation of the hinges and the opening atoneend. v 7

W hen the mold isclosed, the stem G of the eccentric is, by preference, in a vertical position with the mold upon the eccentric, being operated by the attendant for expansion or removal of the mold or the ingot, it will be turned, so that it gradually diminishes in pressure against the mold, thereby quickly allowing the same to expand or to be drawn away. g

K is a projecting piece, which may be cast on or secured to the mold for a hearing. or support for theeocentric lever B.

I claim as my i nventipn The combination, in a mold for casting ingots, of two sections hinged together, and separable at the corners, a strap, 1), hinged to projections E E on one of the sections, and an eccentric, B, carried by the strap, and arranged to bear against the corner of the other section, all as set forth.
